Moin together, father-in-law took advantage of a special pension and bought a SL63 AMG together with his wife and is rather frustrated. The car was bought towards the end of last year, the anticipation was great, the date for the delivery was made and at the handover the car was empty, more precisely the battery. The car was then bridged and started and then the two drove from the yard. After a few meters there are already several warning lights available, ABS except Funkt ion, emergency brake assistant out of function etc. Then the two called the dealer again, who said just continue driving, then the two 2 hours continued driving and then the messages were actually gone someday. But now they have the problem that in the Mercedes ME app every 3-4 days the message comes “battery critical”. So again at Mercedes called, then the battery was checked and found to be ok, car picked up again, still the same Game. Then the car went back to the workshop for diagnosis, then Mercedes has installed a cigarette lighter in the trunk (however they did this, hole drilled etc. but looks quite high-quality from everything). There can now charge the battery via the cigarette lighter. Problem is however still not fixed, every 3 days there is the message in the MBUX and from the 4 day makes the right alarm in the app. Has anyone ever had such a problem? Ic h would type on any control unit that doesn’t shut down or anything else, can’t be normal, right? The car was a demonstration car, had almost 3,000km down, warranty is still available etc.
